So just what is the mission of the church? Is everything mission or does Scripture define our mission more narrowly? DeYoung and Gilbert attempt to answer these questions in their wide-ranging book, which is divided into three main parts relating to defining the church’s mission and our categories, as well as understanding what we do and why we do it. I felt that the methodology of the argument was clear and well-organised, yet the book remained relatively readable. I didn’t agree with all that the authors proposed, although I felt that they should be recognised for their desire to give full importance to the centrality of the gospel of Jesus’ death and resurrection. Particularly to be commended in this book is the sense that the authors have engaged with Scripture in an informed way and as fully as is possible in a book of this size. However, it is perhaps the size of the book which is also its greatest weakness. With fewer than 300 pages, it would be unlikely that this book could give sufficient coverage to the issues it raises and it was my opinion that various matters were treated in an overly-simplistic manner. This unfortunately made me question whether those other aspects of the argument outside of my own expertise were equally simplistic, with the effect that the credibility of this book’s proposal was undermined for me. My views on this one are mixed; maybe you need to read it and make your own mind up!
